It is used for a wide variety of applications, and studies into its efficacy are often of poor quality[2] which makes it difficult to determine efficacy. Several recent meta-analyses and systematic reviews of the literature on various conditions have concluded that the efficacy of hypnotherapy is "not verified",[3] that there is no evidence[4][5] or insufficient evidence[6][7] for efficacy.
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
